Research Abstract	Japanese, Uighur and Uzbek languages are agglutinative and they have various types of inflection. Traditional ways to deal with the inflection are rule-based methods. In contrast to this, we considered inflection is a kind of transliteration and introduced a statistical approach. Thus we tried automatic generation of inflection rules based on statistical machine translation techniques. From this, we obtained the results showing the effectiveness of statistical inflectional processing.
